WITNESSES llWE/VTUR rarer TEXTILE-FINISHING DRUM.

T 0 all whom it may concern.

Be it known that I, Josnrrr LUNEPP, a citizen of the United States, anda resident of South River, county of Middlesex, and State of New Jersey,have invented a new and Improved Textile-Finishing Drum, of which thefollowing is a full, clear, and exact description.

This invention relates to mechanism for the manufacture of textiles, andhas reference more particularly to a finishingdrum for the treatment oflaces and embroideries.

An object of this invention is to provide a finishing drum upon whichlace or embroidery may be wound for the final treatment in varioussolutions, followed by drying.

Another object of this invention is to provide a finishing drum of theclass indicated which will prevent the lace which wound upon it, fromshrinking as the result of treatment in the various solutions anddrying.

Reference is to be had to the accompany ing drawing forming a part ofthis specification, in which it is understood that the drawingillustrates onlyone form of the invention, and in which Figure 1 is aside view of a textile solution tank with parts broken away to disclosethe construction of my improved device.

2 is a central sectional view on a large scale through the finishingdrum.

Fig. 3 is a fragmentary elevation of the finishing drum.

Fig. 4 is a sectional perspective view on a largescale of one of theslats which are used in my preferred form of finishing drum in which theslat is covered with metal such as copper.

Fig. 5 is a sectional perspective view of a modified form of slat inwhich the same is not covered.

Fi 6 is a second modified form of a slat which is circular in crosssection.

Referring to the accompanying drawing by numerals, 10 indicates atextile solution tank which is preferably rectangular in shape, and isprovided with a plurality of partitions 11 which divide said tank intocompartments, each compartment c onta1ning a different liquid such ascaustlc soda, bleaching powder solution, water, etc. Each side of eachcompartment is provided with an open bearing 12 in which is journaled ashaft 13, and said shaft is provided on one Specification of LettersPatent.

end with a belt pulley 14 rotated from any partment, and the bearing 12is of such height that the drum will dip into the solution contained insaid compartment. The drum consists of a pair of annular supports 16which are secured to arms 17 positioned at 90 degrees to each other, andsecured to gether at their intersection. The shaft 13 passes through thearms 17 at their intersection, and the two annular supports 16 arespaced apart at a distance equal substantially to the width of the faceto be treated, by means of parallel strips 18 secured to the arms 17 ofthe two annular supports adjacent the intersection of said arms. A.plurality of slats 19 are provided with offset recesses 20 at each endwhich engage the annular supports 16, and said slats are secured to saidsupports by any suitable fastening means not shown. The slats 19 arepreferably rectangular in cross section with the major axis of the crosssection positioned radially with respect to the shaft 18, and the outeredge of said slats are preferably wedge' shaped where they come incontact with the lace which is wound around the drum. This method ofconstructing slats is especially advantageous since when the co orembroidery goes through a series of solutions and is finally dried. itshrinks considerably, and unless the slats were stiff in the center,they would deflect and permit said shrinkage. However, with the slatsshaped as shown and described, the deflec tion in the center of saidslats will be reduced to a minimum and therefore the loss due toshrinkage of the laces will be practically eliminated. T find that woodis a very good material for use in constructing: my textile drum, andpreferably the slats 19 are covered with a metal coating 21 which may beof copper so that the wear on the slats due to continued and long usewill be reduced to a minimum. I may also make my drum of metal in whichcase the slats 19 will be of solid metal construction as shown in Fig.5. The slats 19 may also be circular in cross section as shown in Fig.6. My improved textile drum is convenient in operation as it may betransferred from one compartment to the other by lifting it from itsbearings 12.

I would state in conclusion that while the illustrated exampleconstitutes a practical embodiment of my invention, I do not limitmyself strictly to the mechanical details herein illustrated, sincemanifestly the same can be considerably varied without departure fromthe spirit of the invention as de I pair of alined annular supports,arms securing said supports to a shaft and spacing them therefrom, aplurality of radially disposed parallel slats connecting the supports,said slats having cutaway portions at each end vforming projections onthe slats located against the periphery of the annular supports, andsaid cutaway portions forming shoulders on the slats located against theinner faces of the supports, and all of said slats including taperingportions adjacent their outer edges.

- 2. Ina textile finishing drum, a pair of annular supports positionedsubstantially parallel and secured to a co-aXially located shaft, aplurality of parallel slats secured around the peripheries of saidannular supports, each of said slats being rectangular in cross sectionWith the major axis of the sections positioned radially with respect tosaid shaft, each of said slats also being wedge shaped on its outer edgeadapted to receive textiles which are wound around said slats, and meansfor rotating said shaft.

3. A device as described in claim 2, characterized by a metal coveringassociated with each of said slats.
